This game is a port of Crowther/Woods adventure that allows switching between English and French.
It was written in the computing language SAM76 and initially released for the CP/M system. (The copy here has the same SAM76 files, but with the interpreter in DOS.) It is the first text adventure that was playable on home computers in a language other than English.
The majority of the implementation was by Jim Manning. Ancelme Roichel (author of the SAM76 language) added some features and wrote the French version, and Harley Licht did testing and verification.
François Brault and Thierry Gauthier also did corrections on the French.
